Two spherical, nonconducting, and very thin shells of uniformly distributed positive charge \( \mathrm{Q} \) and radius \( \mathrm{d} \) are located a distance \( 10 \mathrm{~d} \) from each other. A positive point charge \( \mathrm{q} \) is placed inside one of the shells
\( P \) at a distance \( \mathrm{d} / 2 \) from the center, on the line connecting the centers of the two shells, as shown in the figure. What is the net force on the charge q?
W.
(A) \( \frac{\mathrm{qQ}}{361 \pi \varepsilon_{0} \mathrm{~d}^{2}} \) to the left
(B) \( \frac{\mathrm{qQ}}{361 \pi \varepsilon_{0} \mathrm{~d}^{2}} \) to the right
(C) \( \frac{362 \mathrm{qQ}}{361 \pi \varepsilon_{0} \mathrm{~d}^{2}} \) to the left
(D) \( \frac{360 \mathrm{qQ}}{361 \pi \varepsilon_{0} \mathrm{~d}^{2}} \) to the right
